Sound enhancement device for cell phone

Abstract

A sound enhancing device for improving voice reception of a smartphone microphone is attachable to the rear surface of a smartphone opposite the surface of the smartphone having a display. The device has a deflector in a sliding engagement within a cavity of a housing moveable between a stowed position and a deployed position. A reflective curved area positioned on a first surface of the deflector captures and reflects sound waves from the voice of a user toward a microphone of the smartphone.

What is claimed is: 
     
       1. A sound enhancing apparatus for a smartphone, comprising:
 a housing having an attachment surface; 
 said attachment surface configured for an engagement to a smartphone rear surface or to a portion of a phone case covering said rear surface; 
 a deflector in a sliding engagement with said housing, said deflector movable in said sliding engagement between a stowed position and a deployed position; 
 said deflector having a first surface facing toward said rear surface of said smartphone; 
 said deflector in said deployed position having a projecting portion thereof, said projecting portion extending between said bottom edge of said smartphone to a distal edge of said deflector; 
 a reflective curved area positioned on said first surface of said deflector; and 
 said deflector in said deployed position positioning said reflective curved area to reflect sound waves contacting said reflective curved area toward a microphone of said smartphone. 
 
     
     
       2. The sound enhancing apparatus of  claim 1 , additionally comprising:
 said reflective curved area having a parabolic shape. 
 
     
     
       3. The sound enhancing apparatus of  claim 1 , additionally comprising:
 a first position locator for maintaining the deflector in said stowed position; and 
 a second position locator for maintaining the deflector in the deployed position. 
 
     
     
       4. The sound enhancing apparatus of  claim 1 , additionally comprising:
 a curved section of the deflector at the distal end thereof; 
 said curved section forming a curved endwall; 
 said reflective curved area being elongated and formed upon an area of said first surface positioned upon said curved endwall. 
 
     
     
       5. The sound enhancing apparatus of  claim 4 , wherein said reflective curved area has a radius of substantially 0.35 inches to 0.5 inches. 
     
     
       6. The sound enhancing apparatus of  claim 5 , wherein said reflective curved area has a radius of substantially 0.23 inches and 0.27 inches. 
     
     
       7. The sound enhancing apparatus of  claim 4 , additionally comprising:
 a first position locator for maintaining the deflector in said stowed position; and 
 a second position locator for maintaining the deflector in the deployed position. 
 
     
     
       8. The sound enhancing apparatus of  claim 4 , additionally comprising:
 a notch formed into said endwall, said notch providing a path for engagement of a charging cord to said smartphone; and 
 said notch forming a pathway for sound communication to said microphone with said deflector in said stowed position. 
 
     
     
       9. A sound enhancing apparatus for a smartphone of  claim 1  wherein said reflective curved area is positioned between said distal edge of said deflector and said bottom edge of said smartphone with said deflector located in said deployed position. 
     
     
       10. The sound enhancing apparatus of  claim 9 , additionally comprising:
 a first position locator for maintaining the deflector in said stowed position; and 
 a second position locator for maintaining the deflector in the deployed position. 
 
     
     
       11. The sound enhancing apparatus of  claim 9 , additionally comprising:
 said reflective curved area having a parabolic shape. 
 
     
     
       12. The sound enhancing apparatus of  claim 9 , additionally comprising:
 a curved section of the deflector at the distal end thereof; 
 said curved section forming a curved endwall; 
 said reflective curved area being elongated and formed upon an area of said first surface positioned upon said curved endwall. 
 
     
     
       13. The sound enhancing apparatus of  claim 12 , wherein said reflective curved area has a radius of substantially 0.35 inches to 0.5 inches. 
     
     
       14. The sound enhancing apparatus of  claim 12 , wherein said reflective curved area has a radius of substantially 0.23 inches and 0.27 inches. 
     
     
       15. The sound enhancing apparatus of  claim 12 , additionally comprising:
 a first position locator for maintaining the deflector in said stowed position; and 
 a second position locator for maintaining the deflector in the deployed position. 
 
     
     
       16. The sound enhancing apparatus of  claim 12 , additionally comprising:
 a notch formed into said endwall, said notch providing a path for engagement of a charging cord to said smartphone; and 
 said notch forming a pathway for sound communication to said microphone with said deflector in said stowed position.
